Hi,
EDIT:
I received a bar30 that’s why. problem solved.
Just got a bar02 sensor, and testing it with my arduino using this sketch Guide to Using the Bar02 with an Arduino
I get the following readings in the air, and the same in the water.
(Please not that I didn’t connect a level shifter, but used the 3.3V Vcc pin to power the sensor).
Pressure: 49.00 mbar
Temperature: 29.71 deg C
Depth: -9.86 m
Altitude: 19410.15 m above mean sea level
Pressure: 49.00 mbar
Temperature: 29.71 deg C
Depth: -9.86 m
Altitude: 19410.15 m above mean sea level
Pressure: 49.00 mbar
Temperature: 29.72 deg C
Depth: -9.86 m
Altitude: 19410.15 m above mean sea level
Pressure: 49.00 mbar
Temperature: 29.71 deg C
Depth: -9.86 m

Does that makes sense?
